现代农业科技2023年第19期资源与环境科学光合细菌产氢研究进展姜淑敏汪吉霞王悦佳汪春蕾*(东北林业大学生命科学学院,黑龙江哈尔滨150040)摘要氢气是目前最常用的清洁能源,具有能量含量高和清洁燃烧的特点。制氢的方式有多种,生物制氢与传统物理和化学工艺制氢相比,是最清洁的一种方法。然而,大规模生物制氢的产氢量与产氢率往往受到各种环境等因素的限制。近年来的许多研究突破了环境因素的限制,从微生物代谢、能源来源及微生物产氢关键酶等方面有效提高了微生物产氢效率。本文总结了生物制氢的几种主要方法,详细讨论了光合细菌产氢的影响因素,并对其有效促进途径的研究进展进行了综述,以期为生物制氢领域的深入研究提供参考,为工业大规模制氢、减轻环境污染做出贡献。关键词光合细菌;生物制氮;氢化酶;固氮酶中图分类号TQ116.2文献标识码A文章编号1007-5739(2023)19-0136-07DOI:10.3969/j.issn.1007-5739.2023.19.037开放科学(资源服务)标识码(OSID):ResearchProgressonHydrogenProductionbyPhotosyntheticBacteriaJIANGShuminWANGJixiaWANGYuejiaWANGChunlei*(CollegeofLifeScience,NortheastForestryUniversity,HarbinHeilongjiang150040)AbstractHydrogenisthemostusedcleanenergywithhighenergycontentandcleancombustioncharacteristics.Therearemanywaystoproducehydrogen.Biologicalhydrogenproductionisthecleanestmethodcomparedwithtraditionalhydrogenproductionofphysicalandchemicalprocesses.However,thehydrogenproductionquantityandhydrogenproductionrateoflarge-scalebiologicalhydrogenproductionareoftenlimitedbyvariousfactorssuchastheenvironment.Inrecentyears,manystudieshavebrokenthroughthelimitationsofenvironmentalfactors.Theefficiencyofmicrobialhydrogenproductionwaseffectivelyimprovedfromtheaspectsofmicrobialmetabolism,energyresourceandkeyenzymesrelevanttomicrobialhydrogenproduction.Inthispaper,themainmethodsofbiologicalhydrogenproductionweresummarized,andtheinfluencingfactorsofhydrogenproductionbyphotosyntheticbacteriawerediscussedindetail,andtheresearchprogressoneffectivepromotionapproacheswasreviewed,soastoprovideareferenceforthein-depthresearchinthebiologicalhydrogenproductionfield,andcontributetoindustriallarge-scalehydrogenproduct...
